This thesis examines the discourse strategies of economical news in China Daily and NewYork Times on the tire tariff event from the perspective of critical discourse analysis (CDA). It compares China Daily with New York Times to reveal the ideological difference, and how linguistic elements are shaped by the social and cultural context.This thesis employs Normal Fairclough's three-dimensional model of CDA and incorporates the idea of Holliday's metafunctional grammar in analysis. Fairclough argues that uncovering the way in which discourse operate in society requires a systematic textual analysis, an examination of the processes of production, interpretation of texts and an analysis of the social context in which these texts occur. In the textual analysis, we investigate how linguistic features to express social ideology, such as transitivity, modality, and classification. Different forms result in construting meanings and the patterns of choices are ideologically significant. At the second level, it examines how meaning is generated by the interaction between text and reader. In the analysis of social context, it investigates the institutional, context, situational elements which influence the reports.The study shows that the economic news reports in China Daily and New York Times are also shaped by the different ideologies. News reports not only reflect what happened about the world but also construct the society. Therefore, it is necessary to analyze the relationship between the discourses and ideologies, as well as the consequences produced by such relationship.This study has the following theoretic and practical significance. First, it broadens the research scope of the Critical Discourse Analysis. Secondly, it helps arouse people's cultural awareness. |
